Prótese vascular derivada do látex

Abstract: ResumoContexto: O desenvolvimento de prótese vascular tem sido vital para os avanços e realizações da cirurgia vascular reconstrutora durante as últimas 5 décadas.Objetivos: Desenvolver um novo modelo de prótese vascular microperfurada, confeccionada em tecido recoberto com um composto derivado do látex natural da seringueira (Hevea brasiliensis) e avaliar sua perviedade, trombogenicidade, biocompatibilidade e o processo de cicatrização, além de algumas propriedades mecânicas (adaptabilidade, elasticidade, imp… Show more

“…In skull fractures in rats, the results were similar and the researchers believe that new investigations indicate its use in osteoporosis, odontology and facial bone reconstruction [11]. In [12], they developed a new microperforated vascular prosthesis model, made of tissue covered with a compound derived from rubber tree natural latex (Heveabrasiliensis) and used an expanded a polytetrafluoroethylene prosthesis as control in the contralateral pelvic limb in the same animal. The study was done applying two prostheses in 15 dogs.…”

“…growth of the latex in a study with the use of vascular fabric and drilled latex prostheses into arteries of dogs 2 . Another study used the latex membrane with 0.1% of polylysine in the perineal herniorrhaphy of dogs allowing the occlusion of the hernial ring with granulation during tissue formation and subsequent membrane removal.…”

“…Previous experimental studies with the natural latex biomembrane have proved that it is a biodegradable material of easy preparation and handling, encouraging tissue neoformation (8,9). On this basis, we were interested in investigating collagen development and angiogenesis using this latex graft.…”
